2. Memory

SDRAM: 32MB (standard) / 64MB / 128MB (optional), ECC optional

Flash: 1MB (standard) / 4MB (optional) NOR Flash (firmware / system)

NVRAM: 8KB battery backup + RTC

Expansion: 1×PMC (32bit) + 3×PC-MIP + 1×PCI bridge

3. On-board I/O (much better than 197)

Three, MVME2100 vs MVME197 (one sentence to divide the generation)

MVME197LE/SP/DP: 88K (MC88110), 50MHz, up to 256MB, 10M network, no PMC, old system / spare part

MVME2100: PowerPC (MPC8240), 200–400MHz, up to 128MB, 10/100M network, PMC expansion, new system / upgrade

One sentence: 197 = 88K last generation; 2100 = PowerPC first-generation main force, performance ×3–×5, expansion nature changed.
